: My 16 yr.old son had 2 grand mal seizures about 2 weeks ago. EEG is normal clinically but does have some abnormalities. This is what the dr. told me but couldn't explain what that means. Now his creatanine level is elevated and needs a renal ultrasound. Is this normal with grand mal seizures?Has anyone else had this happen? Is there any other teens out there who can tell me how they are dealing with epilepsy?
